Final answer:
The domain of the function is the set of all possible values for the independent variable, which in this case is x. Option a. {x∣x>0} represents all real numbers greater than 0, which is the correct domain for the function.
Step-by-step explanation:
In this case, the domain of the function is the set of all possible values for the independent variable, which is represented by the letter x. The domain determines the valid inputs for the function.
Looking at the options provided, option a. {x∣x>0} represents all real numbers greater than 0. This means that any value of x that is greater than 0 is a valid input for the function.
Therefore, the correct answer is option a. {x∣x>0}.
